Tokyo radiation back to pre-quake levels

The maximum level of radiation in the Japanese capital has fallen back to normal readings last seen before the March 11th earthquake, the science ministry has said.

Nuclear experts measured the radioactivity in Tokyo for 16 hours through to 9:00am local time yesterday (April 13th) and concluded that the situation has returned to normal, the Associated Press reported.

The Ministry of Education, Culture, Sports, Science and Technology also reported that background radiation has fallen back in Ibaraki and Miyagi Prefectures, although the latter is still experiencing higher than average levels.

Public alarm was raised last month after the earthquake and tsunami led to a crisis at the Fukushima Daiichi nuclear plant.

Despite this, the highest level of radiation recorded outside of the 30km exclusion zone was only half of the amount involved in an average chest X-ray.

Meanwhile, seismologists have told the Yomiuri Shimbun that major aftershocks from last month's earthquake will probably continue to occur over the next few weeks.
